FRANKE Mythos Manual

Product information

Franke Mythos Water Hub Sparkling can filter, cool and carbonize tap water. It offers the option of filtered, chilled and carbonated water from a single tap. Mythos Water Hub All-in-One can furthermore boil tap water. It offers the option of filtered, boiling, chilled and carbonated water from a single tap.

Function of the product

Filter
To ensure good water quality and to protect the product against limescale deposits, a filter must be connected to Franke Mythos Water Hub. The filter reduces unwanted flavor carriers and impurities in drinking water before it is dispensed by means of a flow-through process. The filter material binds heavy metal ions such as lead, copper and cadmium. The integrated activated carbon reduces unwanted turbidity, organic impurities, odors and flavors as well as chlorine residues in the filtrate. Depending on the mineralization and hardness degree of local tap water, a different kind of filter should be used.

Capacity
Franke Mythos Water Hub is equipped with a 425 g CO₂ cylinder that delivers approximately 60 liters of carbonated water. Optionally, an external CO₂ cylinder can be added for higher demands. In that case the pressure reducer of the external CO₂ cylinder has to be adjusted to 5 bar. The input pressure on the unit should never exceed 6 bar. The reservoir of the unit holds 2.2 liters of chilled water, 0.6 liters of carbonated water and an additional 4 liters of pressurized boiled water. The flow rate varies, depending on the water supply pressure and the type of tap. When chilled or carbonated water is dispensed, Franke Mythos Water Hub immediately refills with cold tap water.

Cooling principle
The temperature of the carbonated water depends on the temperature of cooled water in the reservoir. The temperature range of chilled and carbonated water is internally adjusted on the optimal temperature set.

Boiling principle (only for Franke Mythos Water Hub All-in-One system)
The temperature range of boiling water can be adjusted between 60 to 105°C. If the temperature setting is adjusted to 105°C, the tap volume is approx. 2.6 liters above 99°C. For higher output quantities, the hot water temperature will be lower while cold water flows into the boiler during the process of drawing water and begins to mix with the hot water.
Franke Mythos Water Hub does not have a separate boiling water outlet for connecting a mixing valve. If the house installation does not have a hot main water supply that can be directly connected to the tap, it is not possible to draw hot water by adjusting the single-lever mixer on the tap. Alternatively, the temperature of the boiling water can be set between 60 and 105°C using the app.

Carbonation
The CO₂ content of the carbonated water is approx. 5.0 to 5.5 g/l in optimal conditions. This value cannot be adjusted but a mixing with chilled water is possible to reach a lower degree of carbonation. After the withdrawal of carbonated water, there is a short follow-up run of chilled still water to flush the remaining CO₂ out of the line. This function prevents the tap from dripping which is caused physically due to the expansion of CO₂.

Holiday mode
A holiday mode can be activated. Therefore, the device reduces the boiling temperature to 60°C and the temperature of the chilled and carbonated water to 15°C.
Note: The taste and appearance of conditioned water is dependent on many factors e.g. the mineralization and hardness degree of local tap water.
Note: Some tap dripping is normal, especially together with carbonated water. Note: If you are on vacation for more than two weeks, it is recommended to switch off the unit. This is done via unplugging the device or switching it to holiday mode.
Note: If no conditioned water is dispensed for approximately 14 days, we recommend flushing all conditioned water options (filtered, filtered /chilled, filtered/chilled/carbonated, filtered/boiling) for one minute each. This will refill the reservoir with fresh water and ensure optimal water quality.

Connect the plug to a socket complying with current regulation, located in an accessible place.
For Class I appliances, check that the domestic power supply guarantees adequate earthing.
The device requires a permanent air exchange to ensure that the installation site cannot heat up due to the warm exhaust air. An opening in the rear panel of the cabinet or a similar opening in the base plate must be provided.
The power cable shall be laid in such a way that no damage can occur. If the cable or the plug is damaged, it must be replaced by a specialist. If the signal cable to the tap is damaged, the complete tap must be replaced.
A damaged power cable must be replaced with an identical one by Franke or by qualified personnel trained by Franke.
Check the hose supply lines to the tap and the device once a year. A leak at those points will immediately lead to water damage. If necessary, contact the customer service.
All standard CO₂ cylinders without additional flavor with a volume of 425 g and a trapezoidal thread (TR 21×4) may be used in the unit. The actual sealing surface of the CO₂ cylinder should be clean and free of any scratches or dents. When screwing in the cylinder, always ensure that it is fitted tightly. When screwing in, there may be a slight hissing sound and a small amount of CO₂ may escape, which is normal.
CO₂ cylinders are under pressure. Protect them from over heating by direct sunlight or other heat sources. Store the CO₂ cylinder in an environment where heating of the cylinders cannot occur. In case of using an external CO₂ cylinder, the instructions of the supplier shall be strictly followed. The CO₂ cylinder should never be laid down horizontally.
If CO₂ escapes into the room, ventilate the room, and leave it for some time to ensure a sufficient supply of fresh air. Even the total amount inside of a 425 g cylinder is not sufficient to reach lifethreatening concentrations in the air if it escapes.
If you transport the unit, the CO₂ cylinder shall be uninstalled.
Do not use osmosis water or highly filtered water in the system. It can lead to problems in the level control.
It is not permitted to operate Franke Mythos Water Hub without a filter.
If Franke Mythos Water Hub is connected to a water supply with a water softener and the water hardness is below 7°dKH a freshwater filter (Franke Clear Water filter) should be used instead of a standard filter with decalcification (Franke Pro M Connect filter).

Never use serrated tools in order to avoid damage. Where necessary, always use the appropriate tools for tightening the coupling.
Always keep safety tags and notes on the product in a legible condition. Replace damaged safety tags and notes immediately!
At the installation location, Franke Mythos Water Hub must be protected from mechanical damage, heat and direct sunlight, open flames and the danger of frost.
Tiled and stone sinks will not withstand boiling water; the difference in temperature can cause these to crack. Always open the cold water tap when pouring out boiling water and preferably pour the boiling water directly into the drain.
As a result of the ongoing improvement of our products and/or systems, illustrations in this document may differ from the appliance as delivered.

Filter cartridge

The use of a Franke filter is mandatory to protect the product against limescale deposits. It is mandatory to change the filter based on the water hardness table.
After storage at a temperature of 0°C, the filter must first be stored for 24 hours at room temperature before it is installed.
The filter cartridge must not be opened or damaged.
The filter cartridge and the system must be intensively flushed after a prolonged standstill period and/or during maintenance work (2 liters of flushing water after 1 week standstill; 10 liters of flushing water after 4 weeks' standstill).
The filter cartridge must be replaced if, after commissioning, it has not been in operation for 3 months.
